1. Units 1. Perform the following unit conversions (0.5P per conversion): Example: 1 m in [mm] ? 1 m = 1000 mm (a) 154 kg in [t] (b) 20 °C in [K] (c) 3 × 10^8 m/s in [km/h] (d) 9.81 m/s² in [N/kg] (e) 9.8067 Pa in [bar] (f) 17 cm² in [m²] (g) 28.3 l in [mm³] (h) 8 kcal in [kJ] (i) 3 × 10^6 J in [kWh] (j) 2928 ? in [cm²g/h³A²] (k) 1.5 C in [mA h] (l) 0.511 MeV/Particle in [J/mol]

00:01 Hello, in the question we have to perform the unit convergence.

00:04 So the first is 154 kg we need to convert in tons.

00:12 So we know that one 10 is equal to 1 ,000 kg.

00:18 So it will be 1 kg will be equal to 1 divided by 1 ,000 10.

00:23 So this will turn out to be, so this 154 kg.

00:28 So we will get the answer as 0 .154 tons.

00:32 So this is the conversion so we are just dividing by 1000 so now next one is 20 degree celsius we have to convert to kelvin's so in kelvin's the formula is degree celsius plus 273 .15 kelvin so calculating this so we will get the answer as 293 .15 kelvin now the next is 3 into 10 raise to 8 meters per second we have to convert it into kilometer per hour.

01:07 So this is, so we have to multiply this by 18 by 5.

01:12 So if we multiply this by 18 by 5, we get the answer as 10 .8 into 10 raise to 8 kilometer per hour.

01:21 Now next one, the d1.

01:25 In this we have 9 .81 meter per second square.

01:31 This is acceleration and we need to convert.

01:33 Into newton per kg.

01:36 Now there is no conversion needed over here because this newton per kg itself is an dimension of acceleration.

01:42 How newton is unit of force force is equal to mass times acceleration.

01:47 So it is kg meter per second square and this kg is there in denominator...
